For example I can't let my game Tach Chess be open source, as then people would be able to change the rules, etc

It's not impossible to hack into closed source programs. Also, isn't being able to modify rules and tweaking things actually a good thing? (as long as we are not talking about cheating human vs human like in computer games)

Yes I know you can hack straight into an .exe file

And, no, it's not necesarily a good idea to let ppl change the rules, lol
